graphics: REPRESENTATION: item
Polyline and fill area item: the polyline item corresponds to
the coordinate axes, the fill area item is used in 3D diagrams
for the 3 backmost panels of the box.
The fill area item should in principle have an interior style
of "solid" and a light colour. The colour will not be used as
such - rather, various shades will be used depending on the
exposition of the panel with respect to the light source.
Polyline item: clarifying lines such as boundaries.
Text item: the information underneath the title.
Fill area item: conductors in the chamber as entered
with the SOLIDS statement, but also the wires when asking
for a 3D plot of a chamber in which the field is computed
from wire locations rather than a field map.
This representation is used in 3D diagrams. The interior
style should in principle be set to "solid". The colour is
not used as such, rather various shades of it will be used
depending on the exposition of the various surface panels
with respect to the light source.
Fill area item: conductors in the chamber as entered
with the SOLIDS statement and for which a representation
with this type was explicitely requested.

Polyline item: the highlighted contours in the field section
(PLOT CONTOUR) and drift section (TABLE CONTOUR).
Text item: the function values plotted on the contours
if contour labeling has been requested (PLOT CONTOUR LABEL).
Polyline item: the normal contours in the field section
(PLOT CONTOUR) and drift section (TABLE CONTOUR).
Fill area item: the wires of type C are plotted using this
representation if the WIRE-MARKERS option is on.
Fill area item: the dielectrica in the chamber as entered
with the SOLIDS statement.
This representation is used in 3D diagrams. The interior
style should in principle be set to "solid". The colour is
not used as such, rather various shades of it will be used
depending on the exposition of the various surface panels
with respect to the light source.

Polyline item: Electron drift lines.
Polyline and fill area: Error bands plotted with the
PLOT_ERROR_BAND procedure call.
Polyline and fill area: Error bars plotted with the
PLOT_ERROR_BAR procedure call. Also used for the graphs
made by the fitting routines.
Polyline and polymarker item: the primary graph in a plot,
such as PLOT GRAPH or DRIFT TRACK TIME-GRAPH.
Polyline and polymarker: the secondary graph in a plot,
for instance the integrated diffusion in the x(t) plot.
Polyline and polymarker: not yet used.
Polyline used to draw the coordinate grid on the plots.
Polyline item: ion drift lines.
Polyline and polymarker item: the isochrones in a drift
line plot.
With the default settings, an attempt is made to link the
points on an isochrone with lines.
When a point on an isochrone can not be linked to another
point of the same contour, a marker is plotted on the drift
line.
Text item: the labels along the axes. This item is also used
for the '10**n' part of the scaling factor, the exponent is
plotted with the item NUMBER.
Fill area item: used with field maps to draw the area covered
by the material with the lowest dielectric constant.
Fill area item: used with field maps to draw the area covered
by the material with the 2nd lowest dielectric constant.
Fill area item: used with field maps to draw the area covered
by the material with the 3rd lowest dielectric constant.
Fill area item: used with field maps to draw the area covered
by the material with the 4th lowest dielectric constant.
Fill area item: used with field maps to draw the area covered
by the material with other dielectric constants.
Text item: the line asking you to hit return to signal
to the program that it can continue.
Text item: the numbers along the coordinate axes. This item
also covers the exponent if the scale is more than 1 decade.
Fill area item: the wires of type other than S, P and C are
plotted using this representation if the WIRE-MARKERS option
is on.
Polyline item: the outer limits of the solids as shown in
3D and CUT type plots.
Polyline and fill area item: the planes in the cell (PLANE
statement).
The fill area item is used in 3D diagrams. The representation
should in principle have an interior style of "solid". The
colour is not used as such, rather various shades of it will
be used depending on the exposition of the plane with respect
to the light source.
Fill area item: the wires of type P are plotted using this
representation if the WIRE-MARKERS option is on.
Fill area item: the wires of type S are plotted using this
representation if the WIRE-MARKERS option is on.
Text item: the global title of the plot.
Polyline and polymarker item: This can be either of 2 things:
- the straight line segment that you have entered via TRACK
- the series of interaction points with the gas of the particle
that passes through the chamber
The two kinds of tracks coincide unless
- the particle has too little energy to reach the end-point of
the specified line segment
- the particle undergoes multiple scattering and deviates from
its original trajectory
In both cases, the track can be a point in some circonstances.
in that event, a marker is used rather than a line.
Polyline and polymarker item: Delta electrons look like a
hairs along the track. They result from particularly large
energy transfers of the particle to an electron of a gas
molecule. The electrons thus liberated from the molecule
have sufficient energy to ionise further gas molecules before
drifting towards the anodes.
If the delta electron generates several further electrons,
then it will be drawn as a line, otherwise as a marker.
Polyline and polymarker item: Auger electrons result from
the return of an excited atom to a lower energy state by the
emission of an electron rather than a photon - an mechanism
known as Auger effect. The electron that is emitted may have
enough energy to ionise further gas molecules, in which case
these electrons look like delta electrons.
If an Auger electron generates secondary electrons, then a
line is drawn showing its trajectory. Otherwise a marker
indicates the point where it was produced.
Polyline and polymarker item: When a particle ionises a gas
molecule, the molecule can return to its ground state by
emitting a photon, which can be absorbed further on by another
gas molecule.
Polyline item: the tube enclosing the wires (TUBE statement).
Fill area item: Wires are plotted as areas to allow them to
be picked in the GRAPHICS-INPUT instruction. By default, the
wires are plotted such that they look like lines - watch out !
